The expression "'''various authors'''," abbreviated with the acronym
'''Aa.Vv.''', is rarely used in English except by non-native speakers, who look for an exact equivalent to similar terms (usually abbreviated '''Vv.Aa.''') in Italian, Spanish, and some other languages. In English it is much more common to describe the authors of such a compilation collectively, for example by saying for what occasion the texts were written or by naming one writer, for example the first one in the alphabet, and then adding ''et al.
''. The expansion of the acronym is the Latin language|Latin
expression ''auctores varii''.
